Landlords: Stop Painting Over Mould

Why Landlords Should Treat Mould Properly

As a landlord or property manager for residential homes or commercial units, you’ve likely faced the challenge of dealing with mould.

Whether it’s a damp patch in a tenant’s bathroom or a musty corner in a retail outlet, mould is more than just a cosmetic issue – it’s a sign of underlying problems that can have significant consequences. You might think that a quick coat of paint will solve the problem, but here’s the unexpected truth: without proper treatment, you’re only setting yourself up for bigger headaches down the line. By the time you finish reading this article, you’ll understand how to remove mould from walls and ceilings in your property. Treating mould properly is the smartest, most cost-effective approach for both residential and commercial properties, and how it can save you time, money, and stress.

The Hidden Cost of a Quick Fix

Why Just Covering It Up Doesn’t Work

In both residential homes and commercial properties, the temptation to quickly paint over mould can be strong. After all, fresh paint can instantly improve the appearance of a space, whether it’s a family bathroom or a customer-facing retail unit. However, mould isn’t just a cosmetic issue – it’s a symptom of a deeper problem, such as poor ventilation, leaks, or high humidity. When you simply cover it up, you’re not addressing the root cause. Instead, you’re allowing mould to continue growing behind the scenes, where it can cause even more damage to the structure of your property and pose a serious health risk to occupants. This is true for both residential and commercial spaces, where the stakes are high. In a commercial unit, for example, the presence of mould could lead to health concerns for employees and customers, damaging your reputation and potentially leading to lost business.

A Story of Regret

Consider two landlords, each managing different types of properties. The first landlord managed several residential homes and noticed a small patch of mould in one of the bathrooms. Thinking it was a minor issue, he painted over it. Within a year, the mould had spread behind the walls, leading to costly repairs that included replacing drywall and redoing the bathroom. The tenants, frustrated by the disruption, decided to move out, leaving the landlord with an empty property and lost rental income. Furthermore, due to the builder being fully booked, the work was repeatedly delayed, meaning their property couldn’t be rented back out.

The second landlord managed a commercial retail unit. When she discovered mould in the back storage room, she decided to paint over it, thinking it wouldn’t affect the store’s operations. However, the mould soon spread to the main retail area, leading to a musty smell that deterred customers and even caused some staff to experience allergic reactions. The store had to close temporarily for extensive repairs and the company demanded concessions during lease negotiations due to the disruption, resulting in significant financial losses.

 

The Real Solution: Treating Mould Properly

Finding and Fixing the Root Cause

Mould thrives in damp, poorly ventilated environments – whether it’s a residential bathroom or a commercial storage area. The key to effectively treating mould is to identify and address the underlying causes. In residential properties, this might involve fixing leaks, improving bathroom ventilation, or installing a dehumidifier in a damp basement. In commercial spaces, it could mean addressing issues like condensation in poorly ventilated areas, sealing windows and doors properly, or ensuring that HVAC systems are functioning correctly. By tackling these root causes, you remove the conditions that allow mould to flourish, preventing it from returning after treatment.

 

The Power of Specialist Anti-Mould Paints

Once the source of moisture has been addressed, it’s crucial to protect the area from future mould growth. This is where specialist mould-resistant paints come in. These paints aren’t just for show – they’re a long-term solution designed to prevent mould from returning. 

For instance, Zinsser Perma-White Interior Paint is a high-performance product that contains biocides to inhibit mould and mildew growth. It’s suitable for both residential and commercial applications, providing a durable, washable surface that protects walls and ceilings from mould. Its huge colour range – 4,400+ shades in RAL, NCS, and British Standard codes – means existing décor or corporate colour schemes can be easily matched. 

Another suitable product is Glixtone Fungi-Shield Anti-Mould & Black Spot Paint, which is approved by the National Residential Landlords Association (NRLA). 

Using anti-mould paint after treating the affected area means you’re not just hiding the problem – you’re ensuring it doesn’t come back, protecting both your property and your investment.

The Emotional and Financial Impact on Landlords

Protecting Your Investment Property

Whether you’re managing a single-family home or a commercial unit, your property is a significant investment. Properly treating mould is crucial to maintaining the value of that investment. In residential properties, untreated mould can lead to structural damage that requires costly repairs, while in commercial properties, it can disrupt business operations and lead to financial losses. By addressing mould effectively, you’re safeguarding the integrity of your buildings, ensuring they remain desirable places to live or work.

The emotional impact of dealing with repeated mould issues can also be significant. For landlords, this can mean ongoing stress from tenant complaints, the potential for legal disputes, and the constant worry that mould could be causing unseen damage. In commercial settings, the presence of mould can erode the trust of tenants or business partners, leading to strained relationships and potential loss of income. On the other hand, a well-maintained, mould-free property leads to satisfied tenants or business occupants who are more likely to stay long-term, reducing turnover and the associated costs of finding new occupants.

 

How Proper Treatment Builds Trust With Clients

Trust is crucial in any landlord-tenant relationship, whether residential or commercial. Tenants and business clients need to feel confident that their environment is safe and healthy. Imagine a residential tenant who discovers that their landlord simply painted over mould without treating it properly. Not only might they feel deceived, but they could also experience health issues that lead to legal action. Similarly, a business operating out of a commercial unit might lose trust in their landlord if mould issues are handled poorly, leading to potential contract disputes or early termination of leases.

Conversely, when a landlord takes the time to properly treat mould and prevent it from returning, they build trust and demonstrate their commitment to maintaining a high-quality environment. This proactive approach not only keeps tenants and business clients happy but also encourages longer leases, reducing turnover and the time and money spent on remarketing the property.

 

The Unexpected Benefits of Proper Mould Treatment

Saving Time and Money in the Long Run

Many landlords view proper mould treatment as an added expense, but in reality, it’s a cost-saving measure. Addressing the root causes of mould and using specialist paints can prevent frequent repairs and repainting. These are not only expensive but also disruptive to tenants or business operations. Over time, the investment in proper mould treatment pays off by reducing the need for ongoing maintenance. This preserves the property’s value and minimises the risks of vacancy or business disruption.

Enhancing Your Reputation as a Responsible Landlord

In both the residential and commercial rental markets, reputation is everything. Landlords who are known for maintaining safe, clean, and healthy properties are more likely to attract and retain high-quality tenants and business clients. When you treat mould properly, you’re not just protecting your property. You’re also building a reputation as a landlord who cares about the well-being of those who live or work in your spaces. This reputation can lead to higher rental income and better tenant retention rates. It also means less time spent dealing with complaints or vacancies.

Understanding Specialist Mould-Resistant Paints

What Makes Specialist Anti-Mould Paints Effective?

Specialist mould-resistant paints like Zinsser Perma-White and Glixtone Fungi-Shield Anti-Mould & Black Spot Paint are formulated with antimicrobial agents that actively inhibit the growth of mould and mildew. These paints create a barrier that not only resists moisture but also prevents mould from taking hold. They are ideal for both residential and commercial applications. In residential properties, they’re perfect for bathrooms, kitchens, and basements. These are areas typically prone to dampness.

These paints are essential for restrooms, storage areas, food preparation zones, and anywhere else where moisture is a concern. Unlike regular paints, which might temporarily cover mould, mould-resistant paints are designed to provide long-term protection. They help ensure that once the mould is gone, it stays gone.

When and Where to Use Mould-Resistant Paints

Mould-resistant paints should be used in any area where there’s a risk of moisture build-up. In residential properties, this includes bedroom walls, bathrooms, kitchens, laundry rooms, and basements. In commercial properties, areas such as restrooms, locker rooms, storage areas, and food preparation zones are also prime candidates. These spaces are often exposed to high levels of humidity, making them ideal environments for mould to grow if not properly protected. By applying mould-resistant paint, you’re adding a crucial layer of defence that not only enhances the appearance of the property but also ensures its longevity.

How to Apply Mould-Resistant Paint Correctly

To ensure the effectiveness of mould-resistant paint, it must be applied to a properly prepared surface. You must clean mould from walls and ceilings before painting. Here’s how to do it:

1. Prepare the Surface: Clean the affected area thoroughly with a mould-killing solution to eliminate any existing mould. Ensure that the surface is completely dry before moving on to the next step.
2. Fix the Underlying Issue: Address any moisture sources, such as leaks or inadequate ventilation, to prevent the mould from returning. This might involve repairing plumbing issues in a residential property or improving HVAC systems in a commercial unit.
3. Prime if Necessary: For heavily affected or porous surfaces, applying a mould-resistant primer like Zinsser Bulls Eye 1-2-3 can help the paint adhere better and provide extra protection.
4. Apply the Paint: Use a high-quality mould-resistant paint, applying it in even coats according to the manufacturer’s instructions. Ensure good ventilation during application and drying to help the paint cure properly.
5. Monitor for Future Issues: Even after applying mould-resistant paint, it’s important to maintain good ventilation and regularly inspect high-risk areas for signs of moisture or mould. Proactive maintenance is key to keeping your property mould-free.

 

Stories from the Front Lines

The Tale of Two Properties: A Residential Home and a Commercial Unit

Let’s examine two scenarios where landlords took different approaches to mould management in their properties. In the first scenario, a landlord of a residential home noticed a small patch of mould in the bathroom. Believing it was a minor issue, they painted over it without addressing the root cause. Within a few months, the mould had spread throughout the bathroom, causing extensive damage that required significant repairs. The landlord couldn’t get a builder booked in quickly and the tenants, concerned about their health, decided not to renew their lease. This left a vacant property and lost rental income.

In the second scenario, a landlord managing a commercial unit discovered mould in a storage area used by a retail tenant. Rather than opting for a quick fix, the landlord identified the cause of the mould. After repairing the roof and installing better ventilation, the landlord treated the mould with a specialist solution and applied a mould-resistant paint. The retail tenant noticed the improvement and expressed their satisfaction, renewing their lease for another term. This proactive approach saved the landlord from any potential legal issues around damaged stock and health risks, and ensured a steady income stream.
